摘要
城市暴雨特性分析对于研究城市防洪有着十分重要的意义。本文对沧州市2021年最大暴雨过程在时空分布、洼淀蓄水、地下水位、主城区积水等方面进行了定量分析。结果表明,最大暴雨过程产生了河道流量、增加了洼淀蓄水量、抬升了地下水位,使主城区产生了不同程度的积水,该研究成果可为相似类型降雨研究提供依据。同时,为了更好地利用雨洪资源,提出了相关的建议。
The analysis of urban rainstorm characteristics is very important for the study of urban flood control.This paper makes a quantitative analysis on the spatial and temporal distribution,lake storage,groundwater level and water accumulation in the main urban area of Cangzhou City during the heaviest rainstorm in 2021.The results show that the heaviest rainstorm process produced river discharge,increased the lake storage capacity,raised the groundwater level,and produced different degrees of water accumulation in the main urban area.The research results can provide a basis for the study of similar rainfall types.At the same time,in order to make better use of rainfall flood resources,some suggestions are put forward.
